Supplementary Figure 20
Supplementary Figure 20 shows the effect of sICA+FIX cleanup on the Motor Tongue contrast. Top row is the standard analysis (i.e., ‘minimal preprocessing,’ ‘MPP’). Middle Row is after sICA+FIX. The false positive “motor” deactivation in the orbitofrontal cortex is eliminated by sICA+FIX (red oval). This along with several other false positive activations are also visible in the volume slices and are likely related to stimulus-correlated motion. The difference between MPP and sICA+FIX is shown in the bottom row.
